Question

The correct position of the eye is very important for taking measurements. There might be an error in the reading if our eye is not completely in front of the ruler mark. What is the name of this error?

• A. Parallax Error
• B. Oversight Error
• C. Systemic Error
• D. Technical Error

Answer 1

The correct option is A

Parallax Error

The name of this error is Parallax error. It arises when the reading is taken from a random angle instead of taking it normally. It is a non - technical (human) error due to which there is a deviation from the correct readings. So to avoid this error we must always take the readings by positioning our sight perpendicularly above the markings.
